    After enjoying the DRL activated by 2.24.30 for about it week, it looks like my driver side DRL has died. :(

    The top segment is no longer lit (the glare makes it looks like it is partially lit, but actually the whole top segment is dim). The side segment looks fine. I also attached a shot of the passenger side DRL, which is still fully lit top and side.

    This happened right after the 2.24.86 update, but I suspect that's just a coincidence, and it's not just a software issue. Anyone else seen this?

    2.24.86 deactivated BOTH of my DRLs while driving. Everything was working fine after 2.24.30, like you said, and then one little 10-minute update later and my DRLs were gone.

    :(

    The Austin showroom had a facelift on display. Usually the have the parking lights on, but not this time. I turned them on myself. The driver's DRL looked axactly like the one pictured.

    was the turn signal on, or the flashers? I see some yellow down by the fog lights. Many DRL's turn off when one of the turn signals is on.

    The refreshed S in the showroom in Bethesda has the same issue. Driver side out at the top, passenger side fully working.

    I see what is happening. This is another one of Elon's Easter Eggs - the Tesla wink (;>)

    No the yellow down by the fogs is the what I call "Parking Lights" The turn signals are imbedded in the headlights!

    If those orange things are what your talking about then those aren't the reason why the DRL's dim those act as "Parking Lights"!!

    I've seen similar issues with the the DRL'S at various showrooms including the Fremont delivery center. Not sure if the DRL's are blowing out. Considering they are LED I'm surprised it's happening so early.

    Every day I check mine. If they ever seem dim in chunks I'll be sure to bring it to my service center.

    Car got 2.24.102 firmware update today. Was hoping it might be a fix for the dark DRL segment. Unfortunately the problem persists, so at this point I'm assuming it's a hardware failure and will deal with it as part of an already-scheduled service visit in a few weeks.

    Yeah, but as far as from-the-factory defects go, it could have been a lot worse. Been absolutely loving the car otherwise.

    I probably got one of the first units of these new light assemblies, hopefully this isn't too widespread.

    OK - what the heck IS a "DRL"? driver running light? digital reverse lane?

    I've read a dozen threads so far...no one has said what a DRL is.

    DRLs=Daytime Running Lights

    Not only is it safer to drive with DRLs, the DRLs on the refreshed Tesla make the car look even more awesome and stand out even more. They remind me of tiger eyes.

    See @ZeroDarkSilver's Avatar above.

    Yep, same.

    Did it happen to go out right after a software update?

    Thanks everyone -- I'll have to keep an eye out for this defect. Sounds like an issue with the driver or diodes themselves, most likely the former. Seems kind of ironic, since you would hope that an electric car company has nailed how to produce reliable power electronics :D
